The internal optimization capabilities described throughout this chapter are fully integrated with the Ansys Polyflow code, and hence provide the most efficient way to optimize your problem in terms of CPU time and memory usage. Ansys Polyflow also allows you to use other means—namely, the Ansys Workbench tool Design Exploration, and VisualDOC—for exploring solutions and improving your design parameters. These additional means may be useful in some circumstances, and are described in the sections that follow.
